Ngaba iipateni eziprintiweyo zesiko ziya kuchaphazela ukuchasana kwempembelelo yezahlulo zePC?
Izahlulo zePC zaziwa ngokuba "ziipleyiti zentsimbi ezicacileyo" ngenxa yokuchasana kwazo okuhle kakhulu kwaye zisetyenziswa ngokubanzi kukhuseleko lwesixhobo sombane, ulwahlulo lwasekhaya, kunye nezinye iimeko. Ngokunyuka kwesidingo somntu, ushicilelo olulungelelanisiweyo lube yindlela eqhelekileyo yokusetyenzwa kwezahlulo zePC, kodwa abantu abaninzi banenkxalabo yokuba ushicilelo lwepateni luyakwenza buthathaka ukuchasa kwabo. Enyanisweni, le mpembelelo ayikho ngokupheleleyo, kodwa ixhomekeke kwisiphumo esibanzi sobugcisa bokushicilela, ukukhethwa kwezinto eziphathekayo, kunye neenkcukacha zokucubungula.
Ukuchasana kwempembelelo yezahlulo zePC kumiselwa ikakhulu ziipropati zabo eziphathekayo. Ulwakhiwo lwangaphakathi lwe-molecular chain lufana nenethiwekhi ye-elastic, enokuthi ifunxe amandla ngokuguqulwa xa iphantsi kwempembelelo yangaphandle, kwaye ubunzima be-molecular luyimpembelelo ebalulekileyo. Okukhona buphezulu ubunzima bemolekyuli, kokukhona kuqiniswa ukulukwa kwamatyathanga eemolekyuli, kwaye kokukhona ukuchasana kwempembelelo kubhetele. Ushicilelo olwenzelwe wena alutshintshi ubume bemolekyuli ye-PC substrate, ngoko ke ithiyori ayizukonakalisa ngokuthe ngqo ukuqina kwayo. Nangona kunjalo, imisebenzi yenkqubo ngexesha lenkqubo yoshicilelo inokuchaphazela ngokungathanga ngqo ukusebenza.
Ukhetho lwenkqubo yoshicilelo yinto ephambili emisela ukuba ngaba ukusebenza kuyachaphazeleka. Xa ipateni ifakwe ngaphakathi kwezixhobo zePC ezicacileyo, ifilimu eprintiweyo kunye nePC resin zenza ibhondi eyomeleleyo ngexesha lenkqubo yokubumba inaliti. Ayisiyiyo kuphela ipateni yokunxiba kunye ne-fade resistant, kodwa iphinda ingenzi umaleko obuthathaka kwi-substrate surface, kwaye ukuchasana kwayo kwempembelelo kuphantse kungachaphazeleki. Ukuba inkqubo yoshicilelo yomphezulu yemveli ayifanelekanga, inokuzisa iingozi ezifihlakeleyo kwaye yonakalise ulwakhiwo olupheleleyo lomphezulu wePC, yenze izikhewu ezincinci. Ezi zithuba ziya kuba ngamanqaku oxinzelelo ngexesha leempembelelo, ezikhokelela ekunciphiseni kwamandla.
Umgangatho we-inki kunye nezinto ezincedisayo zibaluleke ngokulinganayo. I-inki eyenzelwe ngokukodwa izinto zePC inokwenza ibhondi eyomeleleyo kunye ne-substrate, kwaye ifilimu eyenziwe emva kokumisa iguquguqukayo kwaye i-elastic. Kwanasemva 180 ° ukugoba kwiimvavanyo ukugoba, akukho lula ukuqhekeka, nto leyo enokuthi ihambelane ngokupheleleyo neemfuno deformation ukumelana PC. Olu hlobo lweinki lunokufikelela kwimiphumo yokuhlobisa ngaphandle kokunciphisa ukusebenza kwe-substrate. Nangona kunjalo, i-inki engaphantsi inokuba ne-adhesion eyaneleyo, kwaye umaleko we-inki ulungele ukuxobula xa uchaphazeleka. Isenokuthi ingene kwiikhemikhali kwiPC, echaphazela ngokungangqalanga ukuqina kwemathiriyeli.
Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwakhona kulawulo lokushisa ngexesha lokucubungula. Izixhobo zePC zinobuntununtunu kumaqondo obushushu aphakamileyo, kwaye ukucheba okuphezulu kobushushu kunokubangela ukophuka kwetsheyina lemolekyuli. Emva kokuba ubunzima be-molecular buyancipha, ukuchasana kwempembelelo kuya kuncipha ngokukhawuleza. Ukuba iqondo lokushisa okanye ixesha ngexesha lokumisa emva kokuprinta liphezulu kakhulu, kunokubangela umonakalo ongeyomfuneko we-thermal kwi-substrate ye-PC, ngakumbi kwimveliso yobuninzi. Kuyimfuneko ukulawula ngokuthe ngqo ubushushu bomisa ukuphepha ukulahleka kokusebenza. Ukongeza, iinkcukacha ezinjengokucoceka komphezulu we-substrate phambi kokushicilela kunye nokufana kobunzima be-inki yokwambathisa kunokuchaphazela ukuchasana kwempembelelo yemveliso yokugqibela.
Ngokubanzi, nje ukuba inkqubo efanelekileyo kunye nezixhobo zikhethiweyo, ukwenza iipateni eziprintiweyo ngokwezifiso aziyi kuchaphazela kakhulu ukuchasana kwempembelelo yezahlulo zePC. Ubuchwephesha obuphezulu bunokufikelela kwiziphumo zokukhusela ngelixa uhombisa, ngelixa ushicilelo lwemveli lunokugcina iipropati zokuqala ze-substrate nje ngokuba i-degree etching ilawulwa, i-inki efanelekileyo ikhethiwe, kunye nobushushu bokusebenza bulawulwa. Kwiimeko ezineemfuno zokuxhathisa impembelelo ephezulu, kuyimfuneko kuphela ukubeka phambili inkqubo yokupakisha yangaphakathi yokushicilela kwaye uqinisekise ukuba i-inki iyahlangabezana nemigangatho yemathiriyeli ye-PC, ukuze ulungelelanise ubuwena kunye nokusebenza ngelixa ugcina ukuqina kwesahlulelo sePC.
